Secure wallet for storing assets in a multi-chain, multi-party interface

Abstract

Technologies for providing secure cryptocurrency wallet include a system that receives a request from an external party to conduct a cryptocurrency transaction with a user of a cryptocurrency wallet. The cryptocurrency wallet is instantiated using a public key and a private key. A temporary key is generated based on one or more parameters associated with the wallet. The cryptocurrency transaction is conducted using the temporary key in place of the public key.

1 . A method comprising:
 receiving a request from an external party to conduct a cryptocurrency transaction with a user of a cryptocurrency wallet, the cryptocurrency wallet being instantiated using a public key and a private key;   generating a temporary key based on one or more parameters associated with the wallet; and   conducting the cryptocurrency transaction using the temporary key in place of the public key.   
     
     
         2 . The method of  claim 1 , wherein the temporary key comprises a one-time public key. 
     
     
         3 . The method of  claim 2 , wherein generating the temporary key comprises:
 generating a random nonce;   computing a public nonce associated with the random nonce using a cryptographic algorithm;   computing a shared secret based on a public key of the external party and the random nonce; and   computing the one-time public key as a function of the public key of the external party.   
     
     
         4 . The method of  claim 3 , further comprising:
 including the public nonce in the transaction; and   transmitting the transaction to an address associated with the one-time public key.   
     
     
         5 . The method of  claim 1 , further comprising:
 transmitting the transaction to a pool comprising a plurality of transactions.   
     
     
         6 . The method of  claim 1 , further comprising:
 splitting the private key into a plurality of segments.   
     
     
         7 . The method of  claim 6 , further comprising:
 distributing each of the segments to a plurality of user-selected locations.   
     
     
         8 . A computer-readable storage medium storing a plurality of instructions, which, when executed by one or more processors, causes a system to:
 receive a request from an external party to conduct a cryptocurrency transaction with a user of a cryptocurrency wallet, the cryptocurrency wallet being instantiated using a public key and a private key;   generate a temporary key based on one or more parameters associated with the wallet; and   conduct the cryptocurrency transaction using the temporary key in place of the public key.   
     
     
         9 . The computer-readable storage medium of  claim 8 , wherein the temporary key comprises a one-time public key. 
     
     
         10 . The computer-readable storage medium of  claim 9 , wherein to generate the temporary key comprises to:
 generate a random nonce;   compute a public nonce associated with the random nonce using a cryptographic algorithm;   compute a shared secret based on a public key of the external party and the random nonce; and   compute the one-time public key as a function of the public key of the external party.   
     
     
         11 . The computer-readable storage medium of  claim 10 , wherein the plurality of instructions further causes the system to:
 include the public nonce in the transaction; and   transmit the transaction to an address associated with the one-time public key.   
     
     
         12 . The computer-readable storage medium of  claim 8 , wherein the plurality of instructions further causes the system to:
 transmit the transaction to a pool comprising a plurality of transactions.   
     
     
         13 . The computer-readable storage medium of  claim 8 , wherein the plurality of instructions further causes the system to:
 split the private key into a plurality of segments.   
     
     
         14 . The computer-readable storage medium of  claim 13 , wherein the plurality of instructions further causes the system to:
 distribute each of the segments to a plurality of user-selected locations.   
     
     
         15 . A system, comprising:
 one or more processors; and   a memory storing a plurality of instructions, which, when executed on the one or more processors, causes the system to:   receive a request from an external party to conduct a cryptocurrency transaction with a user of a cryptocurrency wallet, the cryptocurrency wallet being instantiated using a public key and a private key;   generate a temporary key based on one or more parameters associated with the wallet; and   conduct the cryptocurrency transaction using the temporary key in place of the public key.   
     
     
         16 . The system of  claim 15 , wherein the temporary key comprises a one-time public key. 
     
     
         17 . The system of  claim 16 , wherein to generate the temporary key comprises to:
 generate a random nonce;   compute a public nonce associated with the random nonce using a cryptographic algorithm;   compute a shared secret based on a public key of the external party and the random nonce; and   compute the one-time public key as a function of the public key of the external party.   
     
     
         18 . The system of  claim 17 , wherein the plurality of instructions further causes the system to:
 include the public nonce in the transaction; and   transmit the transaction to an address associated with the one-time public key.   
     
     
         19 . The system of  claim 15 , wherein the plurality of instructions further causes the system to:
 transmit the transaction to a pool comprising a plurality of transactions.   
     
     
         20 . The system of  claim 15 , wherein the plurality of instructions further causes the system to:
 split the private key into a plurality of segments; and   distribute each of the segments to a plurality of user-selected locations.
